使用PHP上传文件并添加MySQL数据库路径 [英] Using PHP to upload file and add the path to MySQL database

问题描述

上传.php:

这是表格(在一个单独的文件中):

<p>照片:</p><input type="file" name="文件名"><p>描述</p><textarea rows="10" cols="35" name="Description"></textarea><br/><input TYPE="submit" name="upload" value="Add"/></表单>

错误是

 未定义索引:第 17 行的文件名

($Filename=$_POST['Filename'];)

和

未定义索引:第 35 行上载的文件

(echo "The file ".basename( $_FILES['uploadedfile']['Filename'])." 已上传，并且您的信息已添加到目录中";)

echo"
".print_r($_FILES,true)."</pre>";
给我:
数组([文件名] =>大批([名称] =>Laserkanon.jpg[类型] =>图像/JPEG[tmp_name] =>C:\WampServer\tmp\php11D4.tmp[错误] =>0[尺寸] =>41813))
解决方案
首先你应该使用 print_r($_FILES) 来调试，看看它包含什么.:
您的 uploads.php 看起来像:
//这是保存图片的目录$target = "图片/";$target = $target .基本名称( $_FILES['文件名']['名称']);//这会从表单中获取所有其他信息$Filename=basename( $_FILES['Filename']['name']);$Description=$_POST['Description'];//将文件名写入服务器如果(move_uploaded_file($_FILES['文件名']['tmp_name']，$target)){//告诉你是否一切正常回声文件".基本名称($_FILES['文件名']['名称'])."已上传，您的信息已添加到目录";//连接到你的数据库mysql_connect("localhost", "root", "") 或 die(mysql_error()) ;mysql_select_db("altabotanikk") 或 die(mysql_error()) ;//将信息写入数据库mysql_query("插入图片(文件名，描述)值 ('$文件名', '$描述')") ;} 别的 {//如果不是，则给出错误echo "抱歉，上传您的文件时出现问题.";}?>
由于这是旧帖子，目前强烈建议使用 mysqli 或 pdo 代替php中的mysql_函数
Upload.php:
<?php

//This is the directory where images will be saved
$target = "pics";
$target = $target . basename( $_FILES['Filename']['name']);

//This gets all the other information from the form
$Filename=$_POST['Filename'];
$Description=$_POST['Description'];
$pic=($_FILES['Filename']['name']);


// Connects to your Database
mysql_connect("localhost", "root", "") or die(mysql_error()) ;
mysql_select_db("altabotanikk") or die(mysql_error()) ;

//Writes the information to the database
mysql_query("INSERT INTO picture (Filename,Description)
VALUES ('$Filename', '$Description')") ;

//Writes the Filename to the server
if(move_uploaded_file($_FILES['Filename']['tmp_name'], $target)) {
    //Tells you if its all ok
    echo "The file ". basename( $_FILES['uploadedfile']['Filename']). " has been uploaded, and your information has been added to the directory";
} else {
    //Gives and error if its not
    echo "Sorry, there was a problem uploading your file.";
}
?>
And here is the form(in a separate file):
<form method="post" action="upload.php" enctype="multipart/form-data">
    <p>Photo:</p>
    <input type="file" name="Filename"> 
    <p>Description</p>
    <textarea rows="10" cols="35" name="Description"></textarea>
    <br/>
    <input TYPE="submit" name="upload" value="Add"/>
</form>
The errors are 
 Undefined index: Filename on Line 17
(the     $Filename=$_POST['Filename'];)

and
Undefined index: uploadedfile on Line 35
(the echo "The file ". basename( $_FILES['uploadedfile']['Filename']). " has been uploaded, and your information has been added to the directory";)
echo"<pre>".print_r($_FILES,true)."</pre>";
gives me:
Array
(
    [Filename] => Array
        (
            [name] => Laserkanon.jpg
            [type] => image/jpeg
            [tmp_name] => C:\WampServer\tmp\php11D4.tmp
            [error] => 0
            [size] => 41813
        )

)

解决方案
First you should use print_r($_FILES) to debug, and see what it contains. :

your uploads.php would look like:
//This is the directory where images will be saved
$target = "pics/";
$target = $target . basename( $_FILES['Filename']['name']);

//This gets all the other information from the form
$Filename=basename( $_FILES['Filename']['name']);
$Description=$_POST['Description'];


//Writes the Filename to the server
if(move_uploaded_file($_FILES['Filename']['tmp_name'], $target)) {
    //Tells you if its all ok
    echo "The file ". basename( $_FILES['Filename']['name']). " has been uploaded, and your information has been added to the directory";
    // Connects to your Database
    mysql_connect("localhost", "root", "") or die(mysql_error()) ;
    mysql_select_db("altabotanikk") or die(mysql_error()) ;

    //Writes the information to the database
    mysql_query("INSERT INTO picture (Filename,Description)
    VALUES ('$Filename', '$Description')") ;
} else {
    //Gives and error if its not
    echo "Sorry, there was a problem uploading your file.";
}

EDIT: Since this is old post, currently it is strongly recommended to use either mysqli or pdo instead mysql_ functions in php
